Y., assignor to Frederick Drucker, Richmond Hill, N. it. Application February 8, 1937, Serial No. 124,680 (Cl. 20-565) 1 Glaim.

This invention relates to display refrigerator cases and to such refrigerators, where, in addition to storage room, facilities are provided for the display of the perishable goods under refrigeration through window panes.

The invention is of-the unit type display sec-- tion. The object of the details of construction of said unit is to produce thermal conduction-, and convection-retarding sealed air spaces, allowing one to clean and polish all the applied window panes from time to time as needed, in a practical manner at little or no cost.

In practically all instances the transparency of the sealed air space forming display windows becomes impaired. As time goes on the surface of the windows applied appear clouded, preventing the articles displayed to show up to best advantage. Therefore a practical arrangement to dismount the windows for the purpose of cleaning and polishing same again on the inside surfaces is needed.

The object of the invention resides in the novel details of construction, combination and arrangement of parts, fully set forth in the following description, in connection with the accompanying drawing and particularly pointed out in the appended claim.

In the drawing Fig. 1 is a section on the line l-l Fig. 2.

Fig. 2 is a side elevational view of an assembled display unit.

Fig. 3 is a side elevational view of a display unit inserted in a refrigerator display case.

Fig. 4 is a sectional view of outside spacing moulding E.

Fig. 5 is a sectional view of inside spacing moulding 2 and 3.

Fig. 6 is a sectional view of outside spacing moulding d.

In the drawing, in which like numerals of reference designate like parts in all of the figures, l, 2, d are spacing mouldings having recesses 5 to accommodate window panes 6 and likewise yielding seal gaskets l. These mouldings are of wood or its equivalent, not compressible and so dimensioned to produce in an assembled state a predetermined rigid thickness over all, to comply with the exact and required size for the unit. These gaskets preferably of live rubber are integral units of the non-adhesive type to be inserted with assembly and taken out in dismounting without being damaged, so that they may be used again. Holes ll through all spacing mouldings in one line are to receive bolts it with head it inserted in. recess 8. One end of said bolts is threaded as at E2 to accommodate a nut, 03, to fit in recess 9. In assembling the spacing mouldings with the window panes and seal gaskets, the bolts and nuts serve as assembly means, enabling the spacing mouldings to be held together rigidly as an independent structure in the forming of this display unit. This construction eliminates costly separate and additional frame arrangement. In view of the enclosed airspaces produced between the panes, said unit, serving as display means, is at the same time of low thermal conductivity. It is understood that a plurality of bolts and nuts are needed for one display unit. This display unit as indicated by Fig. 2 is to be inserted into the sill part 16 of a refrigerator display case, gasket l5 serving as seal means.

In this manner one or a plurality of air spaces can be formed, depending upon the number of panes and spacing mouldings used.

Figs. 4, 5 and 6 indicate more clearly the shape of spacing mouldings ll, 2, 3, 4 and the arrangements of same, to hold the window panes with their seal gaskets, and the manner of assembly into a frame unit by means of the bolts and nuts as holding or assembly means.

In case of need for cleaning both sides of the panes, the unit can be taken out of the case; the various parts can be dismounted without disrupting same. In this manner access can be obtained to both sides of the windows for cleaning and polishing purpose, having them again restored to best possible transparency so important for display purposes.

I desire it understood that I do not want to be limited to the specific details of construction V shown or described, as long as the structure or combination of elements come within the terms of the appended claim.

I claim:

In a refrigerated display case with a separately installed display unit, made of a plurality of window panes, spacing mouldings, flexible sealing means and assembly means, the spacing mouldings provided at their contacting sides with recesses, reaching from the moulding edge to a depth slightly above the assembly bolt hole, the end mouldings to have each one recess, and the inside mouldings to have each two recesses, all of the same size, two of said recesses of the contacting mouldings forming in assembly an elongated groove, holding interposed one window pane, flanked by the flexible sealing means, the mouldings to be provided at their center portion with through going holes, properly spaced apart all around and adjacent the periphery of said unit, said holes to line up in assembly, and mark ing a path through all the spacing mouldings, from one side of the unit-to the other side, the outside portion of the end mouldings provided with countersinks at said holes, which are to rerigidly assembied.
